The upcoming downloadable content for Portal 2, the Perpetual Testing Initiative, is rapidly approaching its release.

Valve has provided us with the means to test out the new DLC first hand and we're passing along the goodies to you, our lovely and wonderful community.

This video is a timelapse of the creation of a simple test chamber from start to finish. I provide some commentary to explain what's going on and the options players and designers will have at their disposal.

The end showcases the final, completed map. It also shows just how easy it is to publish to the Steam Workshop.

The Portal 2 Perpetual Testing Initiative releases on May 8 for the PC and Mac.
